Why do you wake up in the morning?

For a long time now, I have been struggling to wake up early in the morning. I recently realized I have no reason to wake up early. There is nothing to do even if I wake up early in the morning :( Lunch is packed on the previous day after dinner (if we cook). I cannot exercise yet, thanks to my injury. I am not expected at work until 10:00PM. What do I do, even if I wake up?
